Use the function is_url (note that I haven't written it) instead to check if the link is a URL. Not only your method may count some links twice, but it will count wrong URLs also. <a href='www.externaldomainnamehere.com'>External</a> is not a URL that will take someone externally.Below is the function is_url function is_url($url) { return preg_match('#^http\\:\\/\\/[a-z0-9\-]+\.([a-z0-9\-]+\.)?[a-z]+#i', $url);} taken from this link: http://plurged.com/code.php?id=26
Hmm, it does only take http links, not https,ftp, etc. Tijnema
